webview-ui/src/i18n/locales/en/settings.json:689, andOllama.tsx:131-142renders the text when a base URL is configured. The changed-file diff contains no visual test or snapshot. The existingOllama.spec.tsxis a Vitest/RTL test and does not provide a Playwright screenshot. No Ollama visual fixture or Ollama screenshot exists under the provider snapshot directory.
Full details: Lifecycle Resource Cleanup
-
Explanation
The changed
completePromptpath still creates two timeout resources. For every positivetimeoutMs, lines 683-695 schedule asetTimeout, and line 726 callsmergeAbortSignalAndTimeout, which creates an additionalAbortSignal.timeout()timer. On a successful short request, thefinallyblock only clearstimeoutIdand removes the external listener (lines 756-760); it never aborts or disposes the native timeout signal. The native timeout can therefore remain scheduled until its deadline. The existing success test checks onlyclearTimeout, so it does not cover this resource.Resolution
Use one cancelable timeout mechanism for
completePrompt. Prefer the existingsetTimeoutto abortrequestController, pass only that controller signal to model discovery, and remove themergeAbortSignalAndTimeoutcall from this path. Alternatively, add explicit disposal for the timeout signal and invoke it infinallyon success, failure, and cancellation. Add a regression test that completes successfully with a long positivetimeoutMsand verifies that the timeout resource is disposed.

- Around line 905-916: Rename the test case around completePrompt to describe
only that no timer is created for a non-positive timeoutMs; remove the
misleading claim about request-local client creation while preserving the
existing assertions.
- Around line 823-846: Update the timeout test around handler.completePrompt to
capture the request-local client instance’s abort spy, then after invoking
capturedFn assert that abort was called once. Replace the ineffective OllamaMock
constructor assertion while preserving the existing timeout capture and setup.
In `@src/api/providers/native-ollama.ts`:
- Around line 398-419: Move the external abort listener cleanup associated with
createMessage into a finally block that encloses the request and streaming
logic, ensuring removeEventListener runs on normal completion, errors rethrown
by the catch block, and early async-generator finalization. Keep the existing
abort bridging and error behavior unchanged.
- Around line 586-611: Move the abort-signal pre-check and listener registration
in the request flow ahead of await this.fetchModel(), matching the ordering used
by createMessage. Ensure pre-aborted signals throw AbortError without fetching
the model, and signals aborted during fetchModel invoke client.abort() and
prevent the request from continuing to client.chat; preserve timeout cleanup
behavior.

Conflict resolved in src/api/providers/native-ollama.ts: main added the model-cache interface (getModelCacheScope + fetchModels, GetModelsOptions / ModelCacheScope / ModelRecord imports) around the legacy ensureClient helper; this branch replaced ensureClient with a per-request _createOllamaClient(requestSignal) for abort bridging. Kept main's two model-cache methods and imports (fetchModels' getOllamaModels call matches the branch's fetcher signature, including the optional signal), and kept the branch's per-request client in place of ensureClient. Verification at this head: 119/119 green across native-ollama.spec.ts and fetchers/ollama.test.ts; tsc --noEmit 0 errors; eslint --max-warnings=0 clean on touched files; prettier clean.
…al help text, deps out - native-ollama.spec: pin the caller side of the transport merge. The new test aborts the caller's signal while the SDK's own fetch signal stays un-aborted and asserts the signal the transport handed to fetch becomes aborted (dropping requestSignal from the AbortSignal.any merge now fails this test, which previously escaped coverage). - fetchers/ollama help text (en locale): state that the API key is only sent to HTTPS or loopback endpoints, so remote HTTP users know the key is omitted rather than silently dropped. - Move the vitest 4.1.11 / @vitest/coverage-v8 bumps (and their lockfile churn) out of this unit per review; they go back up as their own dependency PR. Verification at this head: 120/120 green in native-ollama.spec.ts + fetchers/ollama.test.ts; tsc --noEmit 0 errors; eslint --max-warnings=0 clean on touched files; prettier clean.
The peer alignment touched six manifests; the previous commit reverted only the root and src ones, leaving the lockfile inconsistent with the remaining @vitest/coverage-v8/@vitest/ui 4.1.11 entries (frozen-lockfile installs failed). All manifests now match upstream/main again; the alignment goes back up as its own dependency PR.
…I key
Replace the local raceWithAbortSignal/createAbortError pair with the
shared utils/abort-signal exports (rejectOnAbort +
createAbortError(providerName)), matching openai-codex.ts. The shared
helpers are strictly better shaped: the already-aborted branch
detaches a rejection handler from the pending promise, the listener
registers with { once: true }, and the error carries the provider
name (The Ollama request was aborted) per the series contract. Call
sites that may see an undefined signal (no metadata signal; merged
signal undefined when neither an external signal nor a positive
timeout applies) keep the no-race path explicit. The local helpers
and their dedicated unit block are removed; the shared helpers are
covered by utils/__tests__/abort-signal.spec.ts.
The plain-HTTP credential gate now console.warns when ollamaApiKey
is set but the endpoint is neither https nor loopback, so a bare 401
behind an auth proxy is diagnosable; the warning never echoes the
key. New tests pin the warning (content mentions ollamaApiKey, not
the key) and its absence on secure endpoints. Negative controls:
removing the warn fails exactly the remote-HTTP test (isolated);
mutating the ported provider name fails exactly the already-aborted
completePrompt test.
Verification at this head: 87/87 green in native-ollama.spec.ts; tsc
--noEmit 0 errors; eslint --max-warnings=0 clean with suppression
counts unchanged; prettier clean.

Conflict resolution: keep the branch's completePrompt signature and per-request client/controller setup (upstream's _options variant predates the abort wiring that consumes options.timeoutMs and the abort signal).

Per repo policy (AGENTS.md: Stryker suppression comments are banned; the mutation gate rejects them in touched files). Equivalence arguments for the resulting mutants are recorded in the PR body.
CodeRabbit (security minor): the drop warning interpolated ollamaBaseUrl verbatim, so URL credentials (user:pass@) or sensitive query values in the base URL leaked to the log. The warning now derives the WHATWG origin (protocol//host:port) via new URL() and falls back to a fixed phrase for an unparseable host. Tests cover a base URL carrying credentials and a query token: the warning must contain the origin and must not contain the secret, the token value, or the word "token"; the secure-endpoint test now also pins the attached Authorization header. Negative control: echoing the raw host fails exactly the drop-warning test.
Port of the Zoo-Code-Org#1300 timeout guard finding (CodeRabbit): Node coerces setTimeout delays above 2^31-1 ms (and Infinity) to 1 ms, so completePrompt's timeout could abort almost immediately. The provider guard now requires Number.isFinite and caps the delay at 2^31-1 ms; the shared mergeAbortSignalAndTimeout helper gets the same treatment (AbortSignal.timeout throws ERR_OUT_OF_RANGE on Infinity and clamps overflowing delays to 1 ms, breaking discovery and merged-signal paths). Regression tests: Infinity schedules no provider timer and means "no timeout" in the helper; overflowing values schedule capped timers. Negative controls fail exactly the new tests per revert.

298-302: Credentialed loopback chat can still use a patched globalfetch.The earlier review comment on this transport is still unresolved. The transport reads
globalThis.fetcheach time it builds a per-request client. Model discovery setsproxy: falsefor credentialed loopback HTTP, but chat has no equivalent bypass. If a proxy patch replacesglobalThis.fetchafter activation, a keyedhttp://127.0.0.1chat request sends itsAuthorizationheader through that proxy.src/api/providers/utils/__tests__/abort-signal.spec.ts: 1
279-300: LGTM!
…tion CodeRabbit threads on 2c34c18: - mergeAbortSignalAndTimeout now rounds fractional delays up before AbortSignal.timeout's uint32 validation (1500.5/0.5 threw ERR_OUT_OF_RANGE); regression test for timeoutMs 1.5. - The merged-transport cancellation test asserted its outcome with an if/else that also accepted a post-abort success; controller. abort() is synchronous while rejectOnAbort awaits discovery, so the outcome is always the contract AbortError. Asserted unconditionally plus mockChat-not-called; the old weak form hid a resolve-after-abort regression (negative control: dropping the abort fails exactly this test).

CodeRabbit: the fractional-timeout test only proved the call did not throw and eventually aborted - a round-down mutation (1.5 -> 1) would still pass. The test now spies AbortSignal.timeout and pins the received delay: 2 for 1.5 and 1 for 0.5 (never 0). Negative control: mutating Math.ceil to Math.floor fails exactly this test.

Port of the Zoo-Code-Org#1300 CodeRabbit finding: the raw setTimeout path now applies Math.ceil before the cap so fractional delays round up (1500.5 -> 1501) instead of Node truncating to 1500, matching mergeAbortSignalAndTimeout semantics. New test pins the delay handed to setTimeout; negative control fails exactly that test.

Adds abort-signal support to the native Ollama provider:
completePromptnow honorsCompletePromptOptions.abortSignal/timeoutMs(a pre-aborted signal rejects immediately with anAbortError; mid-flight aborts and timeouts abort the per-request client), andcreateMessagebridgesmetadata.abortSignalinto the per-request client'sabort(). Also ports the per-request_createOllamaClient()refactor (constructorheadersoption for the API key) that replaces theensureClient()singleton.Providers / paths touched:
src/api/providers/native-ollama.ts—completePromptabort/timeout wiring (per-request client, pre-abortedAbortError, abort-listener + timeout cleanup infinally);createMessageexternal-signal bridging into the per-request client;ensureClient()singleton replaced by per-request_createOllamaClient()using the constructorheadersoption forollamaApiKey.src/api/providers/__tests__/native-ollama.spec.ts— reference abort/timeoutcompletePromptsuite and per-request-client suite ported; newcreateMessagebridging tests.src/eslint-suppressions.json— one-line prune:native-ollama.ts@typescript-eslint/no-explicit-any3 -> 2 (removing theensureClient()try/catch dropped one pre-existing violation; the pre-commit lint gate requires the ratchet to match the actual count).Tests added:
completePrompt: request-local client whenabortSignalis provided; no signal-related options when not provided; backward compatible without options;timeoutMsreached triggersclient.abort(); mid-flight abort rejects with "This operation was aborted" (name === "AbortError") and invokes the instance abort; pre-aborted signal aborts immediately and rejects withAbortError; non-positivetimeoutMscreates no request-local timer; abort listener removed and timeout cleared when the signal fires; timeout cleared infinallyon success.createMessage abort signal: pre-aborted external signal -> stream rejects withname === "AbortError"; mid-flight external abort -> per-request clientabort()is invoked and the in-flight stream rejects withname === "AbortError".Ollamaclient percompletePromptcall; API key passed through the constructorheadersoption; noheaderswhen no API key is configured; custombaseUrlhonored.Part of the abort-signal series (round 1). Builds on #674, #901, #1008. Addresses #404.
Updated this round (2026-10-13)
Merged current upstream
maininto the branch to clear the dirty state. One conflict, innative-ollama.ts: main added the model-cache interface (getModelCacheScope+fetchModelsand theGetModelsOptions/ModelCacheScope/ModelRecordimports) around the legacyensureClienthelper; this branch replacedensureClientwith a per-request_createOllamaClient(requestSignal)for abort bridging. Kept main's model-cache methods and imports (fetchModels'getOllamaModelscall matches the branch's fetcher signature, including the optional signal) and the branch's per-request client in place ofensureClient.Verification at this head: 119/119 green across

Three directives removed from
native-ollama.ts:MethodExpression,StringLiteralon the deepseek-r1 detection: the R1 branch and the default branch resolve to numerically identical temperature (DEEP_SEEK_DEFAULT_TEMPERATURE = 0.0), so flipping the detection cannot change the request payload for the covered model ids.LogicalOperator(&& -> ||) inif (onExternalAbort && externalAbortSignal): onExternalAbort is only assigned insideif (externalAbortSignal), so the pair is always set-together or unset-together; && and || agree on every reachable state.if (onAbort && abortSignal)in completePrompt.Credential-drop warning hardening (e7ca0b0)
The CWE-319 drop warning no longer logs
ollamaBaseUrlverbatim: base URLs can embed credentials (user:pass@) or sensitive query values, so only the WHATWG origin (protocol//host:port) is echoed, with a fixed-phrase fallback when the host is unparseable. Tests pin the origin echo and the absence of credential/query material.Timeout guard hardening (2c34c18)
Port of the #1300 CodeRabbit finding: completePrompt's raw timeoutMs guard now requires Number.isFinite and caps the delay at 2^31-1 ms (Node coerces larger/Infinity delays to 1ms, aborting almost immediately). The shared mergeAbortSignalAndTimeout helper gets the same treatment: AbortSignal.timeout throws ERR_OUT_OF_RANGE on Infinity and clamps overflowing delays to 1ms. Regression tests for both layers; negative controls fail exactly the new tests per revert.
Fractional-timeout rounding wave
Follow-up CR round: Node validates AbortSignal.timeout delays as uint32, so finite fractions (1500.5, 0.5) threw ERR_OUT_OF_RANGE like Infinity did. mergeAbortSignalAndTimeout now rounds delays up (a positive fraction never becomes 0 ms) before capping at 2^31-1 ms; regression test mergeAbortSignalAndTimeout(undefined, 1.5). Identical helper patch in every unit of the series (merge-order aware, canonical in #1293).
Also: the merged-transport cancellation test's dead else branch (accepted a post-abort success) replaced with an unconditional aborted-outcome assertion + mockChat-not-called pin.
Assertion strengthening (rounding wave follow-up)
The fractional-timeout test now spies AbortSignal.timeout and pins the received delay (2 for 1.5, 1 for 0.5, never 0) instead of only asserting no-throw plus eventual abort; a round-down mutation (Math.ceil -> Math.floor) fails exactly this test. Identical patch in every unit of the series (canonical in #1293).
Raw-guard fractional rounding (0d18b4d)
Port of the #1300 finding: the completePrompt raw setTimeout guard rounds fractional delays up (Math.ceil) before the cap, matching mergeAbortSignalAndTimeout semantics. Test pins the delay handed to setTimeout (1501 for 1500.5); negative control fails exactly that test.
